If you don't already have the app Dubsmash, you should probably download it right now.
The app takes sound bites from movies, TV shows and popular clips, and it lets you record yourself lip syncing to them. I promise it's way more entertaining than it sounds. Jimmy Fallon can back me up on this. Right, Jimmy?
On Wednesday's episode of "The Tonight Show Starring Jimmy Fallon," Fallon went head to head with Selena Gomez in an epic Dubsmash battle.
Each one took turns lip syncing to the most random sound footage -- from covering the opening of "The Lion King" to John Travolta's "Adele Dazeem." It's definitely worth the watch.
I have to be honest. Gomez totally owned it. Sorry, Jimmy. You gotta pick it up.
Be sure to check out the full battle in the clip above.
